I don't expect the card to be game breaking, although a slow start from our opponent could lead to shutting down songs with "You'll Listen To Me!" being a game winner in certain match-ups
While it can be used to save a couple of creatures from combat or spot removal, there are really two main scenarios which justify including it
That said, I know many people are going to be very excited about the prospect of making tapped treasure tokens every time that they win coin flips
It only stops them on your opponents turn, and even if Pete is removed the effect is still valid
To be honest, Chicha can find a home in any deck with ramp cards, either with item synergies or not
I just love casting removal into removal into card draw, and thats basically all the deck does - perfection
